Unlabelled: To assess the accuracy of BMI compared to directly measured dual-energy X-ray absorptiometry percent body fat (DEXA %BF) among a worker compensation population.
Methods: The agreement between BMI and DEXA %BF was assessed by the Pearson correlation coefficient among 1394 evaluable patients over a 5-year period. Sensitivity and specificity were calculated to measure how well BMI can identify true obese and nonobese individuals.
Results: Using at least 30kg/m to identify obesity, BNI had a specificity of 0.658 and a sensitivity of 0.735. The correlation was better in females at 0.66, compared to males at 0.55, and weaker in older age groups at 0.42, as compared to the youngest age group at 0.59. Overall, 29.8% of the population was reclassified based on their DEXA %BF measures.
Conclusions: In a 5-year cohort worker compensation population, BMI was an inaccurate measure of true obesity.

Background: Targeting cardiovascular fitness (CVF), rather than weight loss, may be a more acceptable and feasible outcome among Latinos.
Purpose: The purpose of this study was to test the short-term efficacy of (AFL), a fitness- and lifestyle-focused behavioral intervention to improve CVF and performance among Latino families.
Methods: Latino parent-child dyads (n = 137) were randomized to either AFL program or a waitlist control condition.
Association Between Handgrip Strength and Muscle Mass in Children 6 to 10 Years Old.

Background And Aims: Sarcopenia, defined as a muscle mass loss and function, is increasingly recognized in pediatric populations, particularly in childhood obesity. Therefore, it is necessary to have measurements that can distinguish between muscle and fat mass. Methods of body composition such as Dual Energy X-ray Absorptiometry (DEXA) provide accurate assessments of body composition, but they are resource-intensive and impractical for routine monitoring in clinical or community settings.

Introduction: Patients with primary hyperparathyroidism (PHPT) are prone to low bone mineral density (BMD). This study aimed to explore factors associated with improved bone health after parathyroidectomy (PTx).
Methods: We conducted a retrospective analysis of patients who underwent PTx for PHPT at our institution between 2016 and 2020.
Hounsfield Unit Utilization in Cervical Spine for Bone Quality Assessment: A Scoping Review.

Bone mineral density (BMD) is an essential indicator of bone strength and plays a crucial role in the clinical management of various spinal pathologies. Hounsfield units (HUs) calculated from computed tomography (CT) scans are a well-established, effective, and non-invasive method to determine bone density in the lumbar spine when juxtaposed to dual-energy X-ray absorptiometry (DEXA) scans, the gold standard for assessing trabecular bone density. Only recently have studies begun to investigate and establish HUs as a reliable and valid alternative for bone quality assessment in the cervical spine as well.
